Symptoms of eye cancer

Eye cancer may not cause any signs or symptoms in its early stages. It is usually found during a routine eye exam. Signs and symptoms often appear as the tumour grows and causes changes to the tissue of the eye or changes to vision. Eye cancer rarely causes pain. Other eye conditions can cause the same symptoms as eye cancer.

See your doctor if you have these signs or symptoms:

an unusual dark spot on the eye, including the coloured part of the eye (called the iris)

vision problems, including blurry vision or loss of vision

seeing floaters (spots, floating objects or squiggly lines)

seeing flashes of light or shadows

change in the size or shape of the pupil (the black-looking round opening in the centre of the iris)
